To receive an electric wave having a plurality of different frequency bands with a conventional high gain.SOLUTION: A vehicular window glass is provided, comprising: a glass plate; an antenna that receives an electric wave with first frequency band and an electric wave with a second frequency band higher than the first frequency band; a defogger of an electric conduction heating type; and a branch element branched from the defogger to an external side of the defogger. The antenna includes: a first element electrically connected to a first power supply unit; a second element electrically connected to the first power supply unit; and a third element electrically connected to a second power supply unit. The first element includes: a first portion extending to a first direction; and a second portion folded from the first portion and extending to a second direction on the side opposite to the first direction. The second element includes a third portion extending to the first direction or the second direction, and the branch element includes a fourth portion arranged in parallel to at least a part of the third portion.SELECTED DRAWING: Figure 2

    【課題】複数の異なる周波数帯の電波を比較的高い利得で受信すること。【解決手段】ガラス板と、第1周波数帯の電波及び前記第1周波数帯よりも高い第2周波数帯の電波を受信するアンテナと、通電加熱式のデフォッガと、前記デフォッガから前記デフォッガの外側に向けて分岐する分岐エレメントと、を備え、前記アンテナは、第1給電部に電気的に接続された第1エレメントと、前記第1給電部に電気的に接続された第2エレメントと、第2給電部に電気的に接続された第3エレメントと、を有し、前記第1エレメントは、第1方向に延伸する第1部分と、前記第1部分から折り返して前記第1方向とは反対側の第2方向に延伸する第2部分と、を含み、前記第2エレメントは、前記第1方向又は前記第2方向に延伸する第3部分を含み、前記分岐エレメントは、前記第3部分の少なくとも一部と並走する第4部分を含む、車両用窓ガラス。【選択図】図2
